1 .2 . Combinations and options
The VRV IV REYQ-T series heat recovery system can be combined
with several types of indoor units and is intended for R410A use only.
For an overview which units are available you can consult the product
catalogue for VRV IV REYQ-T series.
NOTE
To be sure your system setup (outdoor unit + Branch Selector unit(s)
+ indoor unit(s)) will work, you have to consult the latest technical
engineering data for VRV IV REYQ-T series.
An overview is given indicating the allowed combinations of indoor
units and outdoor units. Not all combinations are allowed. They are
subject to rules (combination between outdoor-indoor, single outdoor
unit use, multiple outdoor units use, combinations between indoor
units, etc.) mentioned in the technical engineering data.
The Branch Selector units that combined with REYQ-T units for
changing the refrigerant flow to indoor units are T type
(BSQ-TVJ, BS-Q54TVJ) only. Do not combine the T type and P type
(BSVQ-PVJU, BSV-Q36PVJU) in the system. Combination of T type
and P type cause malfunction.

3 In order to control the cooling or heating operation from a central
location, the following option can be connected:
- Cool/Heat selector: KRC19-26A
- With optional fixing box for the switch: KJB111A
- Centralized control devices (e.g., intelligent Touch Manager)
4 To instruct specific operation with an external input coming from a
central control the external control adaptor (DTA104A61/62) can
be used. Instructions (group or individual) can be instructed for low
noise operation and power consumption limitation operation.
5 For REYQ-T units it is also possible to make several commissioning
field settings through a personal computer interface. For this option
999482P3 is required which is a dedicated cable to communicate
with the outdoor unit. The software for the user interface program
can be obtained from your local Daikin sales office.
